Abstract

3-Hydroxysteroid oxidase controls insects, particularly lepidopterans and boll weevil. Genes encoding for this enzyme may be cloned into vectors for transformation of plant-colonizing microorganisms or plants, thereby providing a method of controlling insect infestation.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method of controlling insect infestation of plants comprising providing a 3-hydroxysteroid oxidase for ingestion by the insect wherein the insect is a lepidopteran or boll weevil. 
     
     
       2. The method of claim 1 wherein the insect is in a larval stage. 
     
     
       3. The method of claim 1 wherein said 3-hydroxysteroid oxidase is the polypeptide of SEQ ID NO:8. 
     
     
       4. The method of claim 1 wherein said 3-hydroxysteroid oxidase is the polypeptide encoded by SEQ ID NO:13 or SEQ ID NO:14. 
     
     
       5. The method of claim 1 wherein said insect is boll weevil. 
     
     
       6. The method of claim 2 wherein said insect is boll weevil. 
     
     
       7. The method of claim I wherein said insect is a lepidopteran. 
     
     
       8. The method of claim 2 wherein said insect is a lepidopteran. 
     
     
       9. The method of claim 1 wherein said 3-hydroxysteroid oxidase is a Streptomyces cholesterol oxidase. 
     
     
       10. The method of claim 1 wherein said 3-hydroxysteroid oxidase is a Pseudomonas cholesterol oxidase. 
     
     
       11. The method of claim 1 wherein said 3-hydroxysteroid oxidase is a Brevibacterium cholesterol oxidase.
